Garland Technology Presents at ISS World for Second Year

May 29, 2015

Garland Technology's German office will be presenting "How to Monitor SSL Traffic." Joined by European Distributor NEOX NETWORKS, Garland's Technical Support Specialist, Patrick Nixdorf, will host this session on Big Data.

ISS_World_Training_logoMay 29, 2015 (PRNewswire) -- Garland Technology, a leading network TAP manufacturer, and NEOX NETWORKS, partner and distributor, are spending the week at the Intelligence Support Systems for Lawful Interception, Criminal Investigations and Intelligence Gathering (ISS) World Conference in Prague, CZ. Patrick Nixdorf, technical support specialist, is presenting on monitoring data and SSL traffic.

Cyber attacks have grown in quantity and severity worldwide, requiring firms and IT professionals to understand exactly what is at stake within their networks. The session's title, "How to Monitor SSL Traffic," is direct – the nature of the presentation will take a complex subject and make it easy to understand, without "removing important technical content," according to CEO Chris Bihary.

"When you are administrator to a network, you have to see every bit of data," Bihary said. "If you decide to let certain types go unchecked, you could be allowing cyber attacks without realizing it. That is why we put this presentation together – people need to know how to monitor SSL traffic."

"How to Monitor SSL Traffic" will focus on the ways that Lawful Interception, Criminal Investigations and Intelligence Gathering IT professionals can – and should – handle encrypted data.

The ISS World Europe conference is "the world's largest gathering of European Law Enforcement, Intelligence and Homeland Security Analysts as well as Telecom Operators responsible for Lawful Interception, Hi-Tech Electronic Investigations and Network Intelligence Gathering." The conference presents methods, tools and solutions for these fields and offers a great opportunity for businesses in these sectors to network and learn from one another.

Heartbeats Packets Inside the Bypass TAP

If the inline security tool goes off-line, the TAP will bypass the tool and automatically keep the link flowing. The Bypass TAP does this by sending heartbeat packets to the inline security tool. As long as the inline security tool is on-line, the heartbeat packets will be returned to the TAP, and the link traffic will continue to flow through the inline security tool.

If the heartbeat packets are not returned to the TAP (indicating that the inline security tool has gone off-line), the TAP will automatically 'bypass' the inline security tool and keep the link traffic flowing. The TAP also removes the heartbeat packets before sending the network traffic back onto the critical link.

While the TAP is in bypass mode, it continues to send heartbeat packets out to the inline security tool so that once the tool is back on-line, it will begin returning the heartbeat packets back to the TAP indicating that the tool is ready to go back to work. The TAP will then direct the network traffic back through the inline security tool along with the heartbeat packets placing the tool back inline.

Some of you may have noticed a flaw in the logic behind this solution!  You say, “What if the TAP should fail because it is also in-line? Then the link will also fail!” The TAP would now be considered a point of failure. That is a good catch – but in our blog on Bypass vs. Failsafe, I explained that if a TAP were to fail or lose power, it must provide failsafe protection to the link it is attached to. So our network TAP will go into Failsafe mode keeping the link flowing.

Glossary

  1. Single point of failure: a risk to an IT network if one part of the system brings down a larger part of the entire system.

  2. Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.

  3. Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
